Elf

Created by the god Corellon, the first elves could change their forms at will. They lost this ability when Corellon cursed them for plotting with the deity Lolth, who tried and failed to usurp Corellon's dominion. When Lolth was cast into the Abyss, most elves renounced her and earned Corellon’s forgiveness, but that which Corellon had taken from them was lost forever.
No longer able to shape-shift at will, the elves retreated to the Feywild, where their sorrow was deepened by that plane’s influence. Over time, curiosity led many of them to explore other planes of existence, including worlds in the Material Plane.
Elves have pointed ears and lack facial and body hair. They live for around 750 years, and they don't sleep but instead enter a trance when they need to rest. In that state, they remain aware of their surroundings while immersing themselves in memories and meditations.
An environment subtly transforms elves after they inhabit it for a millennium or more, and it grants them certain kinds of magic. Drow, high elves, and wood elves are examples of elves who have been transformed thus.

Drow

Drow typically dwell in the Underdark and have been shaped by it. Some drow individuals and societies avoid the Underdark altogether yet carry its magic. In the Eberron setting, for example, drow dwell in rainforests and cyclopean ruins on the continent of Xen'drik.

High Elves

High elves have been infused with the magic of crossings between the Feywild and the Material Plane. On some worlds, high elves refer to themselves by other names. For example, they call themselves sun or moon elves in the Forgotten Realms setting, Silvanesti and Qualinesti in the Dragonlance setting, and Aereni in the Eberron setting.

Wood Elves

Wood elves carry the magic of primeval forests within themselves. They are known by many other names, including wild elves, green elves, and forest elves. Grugach are reclusive wood elves of the Greyhawk setting, while the Kagonesti and the Tairnadal are wood elves of the Dragonlance and Eberron settings, respectively.

Lorwyn-Shadowmoor Elves

Source: Lorwyn - First Light
Elves in the realm of Lorwyn-Shadowmoor possess black, pupilless eyes; curved horns; legs that end in cloven hooves; and pointed ears. The elves of Lorwyn exhibit stark differences physically as well as culturally from their Shadowmoor counterparts.

In Lorwyn

The horns of Lorwyn elves are stubby like a goat’s or curved like a ram’s, but always ridged. Their pointed ears are long and slender.
In Lorwyn, elves value beauty above all, though what any given elf deems beautiful can seem arbitrary. Some Lorwyn elves assume authority over the land’s other peoples, using their fallen empire to support their claims.
These elves blame the fall of their empire on outside threats, especially the Phyrexian invasion. Though the invasion was the empire’s death knell, its people’s self-importance and unwillingness to collaborate with other species had already led to the empire’s decline.

In Shadowmoor

Shadowmoor elves’ horns are long, wavy, and covered with a rough, thorny texture. Their pointed ears are usually longer than those of their Lorwyn counterparts.
Like Lorwyn elves, Shadowmoor elves protect beauty, though a Shadowmoor elf’s definition of “beautiful” can be abstract. Many of their kind believe beauty is gained or lost in accordance with one’s actions; in particular, they consider heroism and self-sacrifice the highest forms of beauty.
Bloomseekers are Shadowmoor elves who study and explore Lorwyn. Each one carries a Reliquary of Twilight. Alongside Safewrights - Shadowmoor elves who venture across their realm in search of beautiful things - Bloomseekers are among the most trusted and revered members of their society.
